Nanotechnology is a multidisciplinary research area and the synthesis of nanoparticles is gaining significance worldwide.
Nanoparticles have a very large surface area which results in greater chemical reactivity, biological activity and catalytic
behavior as compared to larger particles of the same chemical composition. Nanoparticles are used in application such as
catalysts in chemical reactions, electrical batteries and in selective coatings for absorption of solar energy, as optical elements,
pharmaceutical components and in chemical sensing and biosensing. The synthesis of nanoparticles has been reported using
chemical and physical methods. The present study explains a cost effective and ecofriendly approach for the synthesis of silver
nanoparticles (AgNPs) from leaf extract of Mangifera indica. In this study aqueous extracts of the leaves of Mangifera indica used
as reducing and stabilizing agents. Phytochemicals are assumed to be responsible for the formation of AgNPs. The rapid reduction
of silver (Ag+) ions was monitored using UV-visible spectrophotometer. UV-visible spectrum of the aqueous medium containing
silver ions demonstrated a peak value at 440nm. The further characterization of the nanoparticles was done by technique such
as X-RAY diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscope (TEM), Atomic Force
Microscopy (AFM) and Fourier Transform Infrared Spectroscopy (FTIR).
